I was trying to get EHCI running on sequoia board (ppc440epx).

I'm getting the following message when issuing "usb start" .

Cannot enable port 1 after 5 retries, disabling port.

Maybe the USB cable is bad?

Cannot reset port 1!?

1 USB Device(s) found

Scanning bus for storage devices. 0 Storage Device(s)
found

=>

EHCI works fine under operating system (a customized NetBSD). This is the
configuration I'm using,

.

#define CONFIG_USB_EHCI

#define CONFIG_USB_EHCI_PPC4XX /* added ehci-ppc4xx.c similar as
ehci-ixp4xx.c */

#define CONFIG_EHCI_DESC_BIG_ENDIAN

#define CONFIG_EHCI_MMIO_BIG_ENDIAN

Has anybody tried sequoia?
